Abstract:

This study was aimed to analyze the conservation efficiency of Yili goose in reservation farm,and 9 microsatellite markers were used to detect the genetic diversity of three generations (0,1 and 2 generations) of Xinjiang Yili goose.In this experiment,all blood samples were took from three generations of Yili goose.DNA was extracted using phenol-chloroform extraction method,and detected by 12% polyacrylamide gel electrophoresis,silver nitrate staining and judge genotype.The results showed that a total of 78 alleles were detected in 9 microsatellite loci in three generations of Yili goose,26 alleles were detected in 0,1 and 2 generations.The average expected heterozygosity (He) of three generations were 0.4322,0.4232 and 0.4516,respectively.The average polymorphic information content (PIC) were 0.3751,0.3707 and 0.3936,respectively,it showed that three generations of Yili goose were in moderate polymorphism,the genetic variation was at a medium level,and there was no significant difference in average He and PIC among three generations (P>0.05).The genetic distances of three generations were 0.0097,0.0184 and 0.0074,respectively.In conclusion,Yili goose had rich genetic diversity,and the current conservation method adopted by the conservation farm had better preserved the original genetic diversity of Yili goose.
